" When a project or meeting gets difficult, it can be tempting to power through to try to get it over with.
But it's better to do the same you might do for a slow-moving computer: shut it off and wait a minute
Give yourself the opportunity to regain your composure. In a meeting that's going nowhere?
Take a break. Not making headway on that proposal you need to write?
Take a walk. During the break, don't think of new strategies or arguments. By taking yourself out of the situation, you allow your brain to rest so that when you return—with a fresh perspective and a calm mind—
you are more likely to find a new solution. "
From "Restore Yourself to Your Factory Default Settings" by Peter Bregman.
